Closed-loop DC characteristics of the organic OPAs. (a) The circuit diagram and (b) the characteristics of the voltage follower. (c) The circuit diagram and (d) the characteristics of the non-inverting amplifier. The resistance R1 was fixed at 100 MΩ. (e) The dependence of closed-loop gain on R2 for the non-inverting amplifiers. Dashed line indicates the calculation based on Eq. 2 with an open-loop gain of 30.
